Ok guys I just ran to the store to grab a couple things. It was 47 degrees out and raining. I opened her up a couple times and never hit 16psi peak boost. The peak I got was 15 psi then it was steady...

I Have A Bone Stock 09 Subaru Wrx, And Was Wondering How Much Boost Spike Is To Much. My Boost Spikes To 16 Psi Then Drops To A Stead 13.5 Psi. I Was Told By A Local Shop That The 16 Psi Was To High....
